We are pleased to be able to present the Ninth Edition of Fan Engineeringwhich is recognised worldwide as THE definitive handbook on fan design and fan applications, and reflects our lengthy experience with fan design.

Fan Engineering has been written as a handbook for engineers who use fans. It is organised into four parts.

Fan Engineering: Robert Jorgensen: : Books

The name Howden has been associated with the fan industry since the early days of the industrial revolution. James Howden began his consulting business in His patent for a method of preheating combustion air led to the design of mechanical draft systems in During the last half of the nineteenth century the B. Each made valuable contributions to the art and science of fan engineering as did those which followed in the twentieth century like Ventilatoren Stork, Nordisk Ventilator Company, Voith, and Novenco Industries.

Beginning inHowden began a program to acquire the finest fan companies around the world. As a result, the Howden portfolio of products fxn the best of the following: The Howden Engineerring markets fans throughout the world. The thermodynamic and transport properties of gases and vapors are important in fan engineering.


This chapter deals with the thermodynamic properties, especially pressure, temperature, humidity, density, and enthalpy Transport properties, such as viscosity, thermal conductivity, and diffusivity, are dealt with in subsequent chapters.

Fan Engineering; Sixth Edition

The gaseous materials most frequently encountered in fan engineering are air and water vapor; accordingly, most of the data are for handbookk substances.

Some formulae have been written specifically for these materials, but most are generalized to accommodate any gas. Atmospheric air is a mixture of dry air, water vapor, and impurities. Dry air is a mechanical mixture of gases, whose principal constituents are listed in Table 1. The table values may be considered representative of the composition of normal outdoor air throughout the troposphere.

The amount of water vapor in atmospheric air will depend on weather conditions.

The nature and amount of impurities in the atmosphere depend on the forces at work in producing and dispersing contaminants. Industrial, urban, rural, seaside, and other areas have characteristic atmospheres due to differences in impurities.

The reference for Table 1.

ASHRAE considers all these gases in the calculation of the apparent molecular weight of clean, dry atmospheric air and obtains a value of Rounding off and lumping the residuals with the nitrogen, as has been done in Table 1.

Fan Engineering Handbook

Part I deals with fundamental topics. Although these topics are generally treated in other handbooks, they are presented here for the convenience of the reader.


Each subject has a bearing on howdenn or fan applications. Part II is about fans. Although there is some discussion of fan design, both aerodynamical and mechanical, the emphasis is on those topics which should concern the user. Even those portions which are concerned with design may be valuable to the user, since an understanding of what makes a fan work may lead to better applications.

Part III is concerned with specific fan applications. Here too, the convenience of the reader is the main reason for including several of these topics.
